♦ Flow past an airfoil at high angle of attack shortly after a sudden start of motion. A marginal separation near the leading edge is followed by reattachment. The starting vortex is clearly seen.

♦ Flow past the same airfoil at a later time. There is a substantial region of separation.

♦ And even later.

♦ This is an early stage of the development of the Karman vortex street behind a circular cylinder.

♦ Flow past a car.

♦ This is a spatially developing Karman vortex street: further downstream the vortices will gradually arrange themselves into the usual mutual position.

Welcome to Flow Illustrator

This is an easy to use online tool to simulate fluid flow around objects. If you would like to make a video of the fluid flow around an object take a look at our guide on creating your image. Once you are ready you can make your video on this page. If you would like to know more about the parameters used on the page they can be found here.
